What is this?
This package is a unified (remark) plugin, specifically a remark-lint
rule. Lint rules check markdown code style.
When should I use this?
You can use this package to check that ordered list values are consistent.
Presets
This rule is included in the following presets:
Preset | Setting |
---|---|
remark-preset-lint-markdown-style-guide | 'one' |
Install
This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:
npm install remark-lint-ordered-list-marker-value
In Deno with esm.sh
:
import remarkLintOrderedListMarkerValue from 'https://esm.sh/remark-lint-ordered-list-marker-value@3'
In browsers with esm.sh
:
<script type="module">
import remarkLintOrderedListMarkerValue from 'https://esm.sh/remark-lint-ordered-list-marker-value@3?bundle'
</script>
Use
On the API:
import {remark} from 'remark'
import remarkLint from 'remark-lint'
import remarkLintOrderedListMarkerValue from 'remark-lint-ordered-list-marker-value'
import {read} from 'to-vfile'
import {reporter} from 'vfile-reporter'
const file = await read('example.md')
await remark()
.use(remarkLint)
.use(remarkLintOrderedListMarkerValue)
.process(file)
console.error(reporter(file))
On the CLI:
remark --use remark-lint --use remark-lint-ordered-list-marker-value example.md
On the CLI in a config file (here a package.json
):
…
"remarkConfig": {
"plugins": [
…
"remark-lint",
+ "remark-lint-ordered-list-marker-value",
…
]
}
…
API
This package exports no identifiers. The default export is remarkLintOrderedListMarkerValue
.
unified().use(remarkLintOrderedListMarkerValue[, config])
This rule supports standard configuration that all remark lint rules accept (such as false
to turn it off or [1, options]
to configure it).
The following options (default: 'ordered'
) are accepted:
'ordered'
— values should increment by one from the first item'single'
— values should stay the same as the first item'one'
— values should always be exactly1
Recommendation
While 'single'
might be the smartest style, as it makes it easier to move items around without having to renumber everything and doesn’t have problems with aligning content of the 9th and the 10th item, it’s not used a lot and arguably looks unnatural. 'one'
is like 'single'
but forces every list to start at 1
. While not often needed, starting lists at other values is sometimes useful. Due to this, 'ordered'
is recommended, although 'single'
is also a viable choice.
Fix
remark-stringify
retains the value of the first item and increments further items by default. Pass incrementListMarker: false
to not increment further items.
Examples
ok.md
In
The default value is `ordered`, so unless changed, the below
is OK.
1. Foo
2. Bar
3. Baz
Paragraph.
3. Alpha
4. Bravo
5. Charlie
Unordered lists are not affected by this rule.
